Trihydrophobin 1 attenuates androgen signal transduction through promoting androgen receptor degradation

The androgen‐signaling pathway plays critical roles in normal prostate development, benign prostatic hyperplasia, established prostate cancer, and in prostate carcinogenesis. In this study, we report that trihydrophobin 1 (TH1) is a potent negative regulator to attenuate the androgen signal‐transduction cascade through promoting androgen receptor (AR) degradation. TH1 interacts with AR both in vitro and in vivo, decreases the stability of AR, and promotes AR ubiquitination in a ligand‐independent manner. TH1 also associates with AR at the active androgen‐responsive prostate‐specific antigen (PSA) promoter in the nucleus of LNCaP cells. Decrease of endogenous AR protein by TH1 interferes with androgen‐induced luciferase reporter expression and reduces endogenous PSA expression. Taken together, these results indicate that TH1 is a novel regulator to control the duration and magnitude of androgen signal transduction and might be directly involved in androgen‐related developmental, physiological, and pathological processes.

Monoubiquitylation in the Fanconi anemia DNA damage response pathway

The hereditary genetic disorder Fanconi anemia (FA) belongs to the heterogeneous group of diseases associated with defective DNA damage repair. Recently, several reviews have discussed the FA pathway and its molecular players in the context of genome maintenance and tumor suppression mechanisms [H. Joenje, K.J. Patel, The emerging genetic and molecular basis of Fanconi anaemia, Nat. Rev. Genet. 2 (2001) 446–457; W. Wang, Emergence of a DNA-damage response network consisting of Fanconi anaemia and BRCA proteins, Nat. Rev. Genet. 8 (2007) 735–748; L.J. Niedernhofer, A.S. Lalai, J.H. Hoeijmakers, Fanconi anemia (cross)linked to DNA repair, Cell 123 (2005) 1191–1198; K.J. Patel, Fanconi anemia and breast cancer susceptibility, Nat. Genet. 39 (2007) 142–143]. This review assesses the influence of post-translational modification by ubiquitin. We review and extract the key features of the enzymatic cascade required for the monoubiquitylation of the FANCD2/FANCI complex and attempt to include recent findings into a coherent mechanism. As this part of the FA pathway is still far from fully understood, we raise several points that must be addressed in future studies.

Program-like aging and mitochondria: instead of random damage by free radicals

As recently suggested, the target of rapamycin (TOR) pathway, rather than molecular damage by free radicals, drives aging and diseases of aging. But may mitochondria nevertheless contribute to aging? Here, I discuss aimless program‐like aging (versus altruistic program), conflict between the cell and mitochondria, cell murder (versus cell suicide) and the role of mitochondria in aging. In particular, life‐long selection among mitochondria may yield “selfish” (malignant) mitochondria resistant to autophagy. And TOR may create an intra‐cellular environment that is permissive for such selfish mitochondria. In theory, pharmacologic inhibitors of the TOR pathway may reverse accumulation of defective mitochondria, while also inhibiting the aging process. J. Cell.

A lipid transfer protein that transfers lipid

Very few lipid transfer proteins (LTPs) have been caught in the act of transferring lipids in vivo from a donor membrane to an acceptor membrane. Now, two studies (Halter, D., S. Neumann, S.M. van Dijk, J. Wolthoorn, A.M. de Maziere, O.V. Vieira, P. Mattjus, J. Klumperman, G. van Meer, and H. Sprong. 2007. J. Cell Biol. 179:101-115; D'Angelo, G., E. Polishchuk, G.D. Tullio, M. Santoro, A.D. Campli, A. Godi, G. West, J. Bielawski, C.C. Chuang, A.C. van der Spoel, et al. 2007. Nature. 449:62-67) agree that four-phosphate adaptor protein 2 (FAPP2) transfers glucosylceramide (GlcCer), a lipid that takes an unexpectedly circuitous route.     

Contribution of the fibrinolytic pathway to hematopoietic regeneration

Hematopoietic stem cells (HSCs) can differentiate and proliferate in response to hematopoietic stress (e.g., myelosuppression, infections, and allergic reactions), thereby ensuring a well‐regulated supply of mature and immature hematopoietic cells within the circulation and prompt adjustment of blood cell levels within normal ranges. The recovery of tissues and organs from hematopoietic stress (e.g., myelosuppression or ionizing irradiation) is dependent on two cell types: resident HSCs which repopulate the bone marrow (BM) cavity, and stromal cells. BM regeneration critically depends on the release of soluble factors from cells such as stromal cells, a process regulated by proteases. Two proteolytic systems, the fibrinolytic system and the matrix metalloproteinases (MMPs), have recently been shown to be involved in this process (Heissig B, 2007, Cell Stem Cell 1: 658–670). The plasminogen/plasmin system is mostly recognized for its fibrinolytic activity, but it is also involved in processes such as cell invasion, chemotaxis, growth factor activity modulation, and tissue remodeling. This review focuses on the role of plasmin and its activators as key players in controlling the hematopoietic stress response after myelosuppression (hematopoietic regeneration). Aspects of plasmin regulation, especially regulation of its ability to activate MMPs and the functional consequences of this enzyme activation, such as plasmin‐mediated release of biologically relevant cytokines from the matrix and cell surfaces, will be discussed.
